Like it or not, our work lives involve meetings - status meetings, planning conference calls, brainstorming sessions, meetings for the sake of meetings. But a meeting is only as valuable as the action taken after everyone's left the conference room.

Whether you're headed off to a business meeting, a university lecture, or a conference session, taking effective notes is a necessary skill to move your projects, your career and your education forward. Today I'll go over a couple of my favorite note-taking methods, as well as how to make your own custom notepaper to fit your needs.

The first two methods are especially useful for business meetings and professional conferences, where it's most important to separate different types of information.

Method 1: Symbolize the next action

Using notepaper or a simple text file on your laptop or tablet, indent the pages of your notes in from the left margin. Then, use a simple system of symbols to mark off 4 different information types in the column space left in the margin.

[ ] A square checkbox denotes a to do item

( ) A circle indicates a task to be assigned to someone else

* An asterisk is an important fact

? A question mark goes next to items to research or ask about

After the meeting, a quick vertical scan of the margin area makes it easy to add tasks to your to do list and calendar, send out requests to others, and further research questions. (This method is the brainchild of Michael Hyatt, someone who clearly has mastered the art of attending meetings.)

Method 2: Split your page into quadrants

Another way to visually separate information types is to split your note-taking page into quadrants and record different kinds of information - like questions, reference and todo's - into the separate areas on the page. Rumor has it this is how Bill Gates - someone known for taking amazingly detailed meeting notes - gets it done.

Method 3: Record and summarize - The Cornell Note-taking Method

A system more targeted towards students digesting large amounts of information on a daily basis, the Cornell note-taking method also separates the page into different areas, as pictured:

Note taking area: Record lecture as fully and meaningfully as possible.

Prints pages split up into the Cornell notepaper style with unlined, ruled or graphed sections. Optionally include your name, the date, and the name of your class, and up to 4 punch holes for use in a binder. Also, choose the line darkness on a scale from gray to black.

This PDF notes template includes your name, number, the date, project name and splits the page into two sections: one for notes (with lines) and the other for action items with due dates, with optional punchholes.
